19. Having Unprotected Sex
Sex has several health benefits, like reducing stress and boosting your immune system. However, having unprotected sex also comes with its own dangers. Most notably, having unprotected sex puts you at risk for contracting STIs like HPV and chlamydia, both of which have been linked to increased cancer risk.
Because both of these STIs can have subtle symptoms – or none at all – it’s essential to be regularly tested if you are engaging in unprotected sex. The easiest way to prevent exposure to these STIs is, of course, using protection.
